you may receive the following error message:Note If you repeat either one of the previously mentioned methods to send an e-mail message from Word, you can send the e-mail message from Word as expected.

This problem may occur if one of the following conditions is true:

• You installed a Microsoft Office Outlook COM add-in that opens a message box in the OnConnection event of the add-in. This action causes the OnConnection event to run when Microsoft Office Outlook 2003 starts.
• You implemented a Microsoft Outlook Visual Basic for Applications (VBA)code that displays a message box in the Application_StartUp event.

To work around this problem, use one of the following methods:

• Start Outlook before you try to send an e-mail message from Word.
• Do not use the Outlook COM add-in or the VBA code that is causing the message box to appear when Outlook starts.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
